摘要: 描述交流勵磁工頻同步化調速電機的結構,對其矢量控制系統、循環變流器、交流勵磁工頻同步化調速電機進行了仿真數值分析.結果表明,變頻側定子力矩電流在突加負載時僅有微小變化,速度響應的超調量也比較小,電機工頻側定子磁鏈比較平滑,未受動態過程的影響,具有較強的魯棒性.仿真分析與實驗結果達到較好的吻合.

Abstract: The key structure of an Ac excited grid frequency synchronized machine (AEGFSM) was presented. The simulation of AEGFSM, cyclo-converter, field-oriented vector control algorithm was done according to their discrete mathematical model. An AEGFSM sample drived was fabricated. Simulation results are in excellent agreement with the experimental under the typical working condition. It is concluded that AEGFSM drives have the high-quality dynamic performances as DC drives and provide an applicable solution of middle-voltage freqency-variable drives. -
